Ingredients

For the Onion Rings:

• 2 large white onions
• 1 cup shredded mozzarella cheese
• 1 cup all-purpose flour
• 2 large eggs, beaten
• 1 cup breadcrumbs (plain or panko for extra crunch)
• ½ cup grated Parmesan cheese
• Salt and black pepper, to taste
• Vegetable oil, for frying (or cooking spray for baking)

For the Garlic Butter:

• ¼ cup unsalted butter
• 2 cloves garlic, minced
• 1 tablespoon chopped parsley (optional)
• A pinch of salt

Time

• Prep: 20 minutes
• Cook: 15 minutes
• Total: 35 minutes
• Serves: 4–6

Instructions

Step 1: Prepare the Onions

1. Peel the onions and slice them into thick rings (about ½-inch wide).
2. Separate the rings carefully and pair one large ring with one slightly smaller ring — you’ll stuff cheese between them.

Step 2: Stuff with Mozzarella

1. Place a bit of shredded mozzarella cheese between two onion rings (the smaller one nested inside the larger one).
2. Press gently to form a tight seal — the cheese should be completely enclosed between the rings.
3. Repeat with remaining onion rings and freeze for 15–20 minutes to help them hold their shape.

Step 3: Coat for Frying

1. In three shallow bowls, prepare your breading station:
   • Bowl 1: Flour (seasoned with a little salt and pepper)
   • Bowl 2: Beaten eggs
   • Bowl 3: Breadcrumbs mixed with Parmesan cheese
2. Dip each stuffed onion ring first in flour, then egg, then breadcrumbs, making sure to coat thoroughly.
3. For extra crispiness, repeat the egg and breadcrumb step a second time!

Step 4: Fry (or Bake)

 To Fry:

1. Heat oil in a deep skillet or pot to 350°F (175°C).
2. Fry onion rings in batches for 2–3 minutes per side, or until golden brown and crispy.
3. Transfer to paper towels to drain excess oil.

 To Bake or Air-Fry:

• Bake: Preheat oven to 425°F (220°C). Place rings on a parchment-lined baking sheet and spray lightly with oil. Bake for 15–18 minutes, flipping halfway.
• Air-Fry: Cook at 400°F (200°C) for 10–12 minutes, until golden and crisp.

Step 5: Make the Garlic Butter

1. In a small saucepan, melt the butter over medium heat.
2. Add the minced garlic and cook for about 1 minute, until fragrant (don’t let it brown).
3. Stir in parsley and a pinch of salt.

Step 6: Serve & Enjoy

Arrange the mozzarella-stuffed onion rings on a platter and drizzle with warm garlic butter.
Serve with marinara sauce, ranch dressing, or spicy aioli for dipping.

Tips for Success

• Freeze before frying — helps the cheese stay inside and prevents leaking.
• Use panko breadcrumbs for extra crunch.
• Try adding a little Italian seasoning or smoked paprika to the breadcrumb mix for flavor.
• Don’t overcrowd the pan when frying — they crisp better in small batches.

Storage

• Store leftovers in an airtight container in the fridge for up to 2 days.
• Reheat in an oven or air fryer for 5–7 minutes to restore crispiness (avoid microwaving — it softens the coating).
